The lead member of the design team, the New York firm of Kohn Pedersen Fox Associates, considered two historical regional influences when they designed the new terminal: the architecture of Frank Lloyd Wright, and the importance of aviation and flight to the region. They envisioned a crystalline structure symbolizing flight - and that vision became a reality. Some 27,000 square feet of glass dominate the 350-foot-wide lobby with its 50-foot ceiling and arching walls. When looked at from the air, the terminal itself looks like a giant aircraft poised for flight. Within the main Gateway concourse, a unique 13,000-square-foot work of art has been created on the floor with multicolored terrazzo tiles depicting the history of the region from a geological and sociological perspective. Created by Oregon artist and sculptor Robert E. Calvo, the woven pattern in the center of the design serves as a metaphor for the region, which was created out of the influences of many divergent events. Source: www.nfta.com/airport/ppf.phtml
